I loved this! I felt like I was a Pokemon NPC from the older gameboy color games. I like the way you laid out the level, it became very clear really fast that people follow you like in Snake (I guess the title helped explain that as well haha).
One suggestion: Consider making the floor tiled and giving the characters a shadow so that it is more clear if they are going to crash into something. I think the 3d-ish effect makes it slightly hard to tell if something will be hit.
Overall great job!
